Enclosed-type cellular shade structure

ABSTRACT

An enclosed-type cellular shade structure includes a plurality of interconnected cellular pieces uniformly arranged from top to bottom and fixed between a head rail and a bottom rail to form an enclosed-type cellular shade with free ends disposed at both end edges thereof, permitting the cellular pieces to be raised or lowered by a lift cord wherein both side edges of each cellular piece are defined by a long bent section and a short bent section that are respectively equipped with a coupling end and a fixing end to be securely attached to the bottom surface of each immediate upper cellular piece thereby. Therefore, when the cellular shade is fully expanded, the short bent sections thereof will be appropriately stretched into a flat surface, economically saving both time and efforts in cleaning as well as reinforcing a uniform expansion of the cellular pieces to achieve the best application state thereby.

BACKGROUND OF THE INVENTION

The present invention is related to an enclosed-type cellular shade structure, including a plurality of interconnected cellular pieces uniformly arranged from top to bottom and fixed between a head rail and a bottom rail to form an enclosed-type cellular shade wherein both side edges of each cellular piece are defined by a long bent section and a short bent section with a coupling end and a fixing end respectively disposed thereon so that, when the cellular shade are fully expanded, the short bent sections thereof will be appropriately stretched into a flat surface to support the long bent sections thereof unfolding in an even and consecutive transverse V-shaped patterned surface, economically saving both time and efforts in cleaning as well as reinforcing a uniform expansion of the cellular pieces to achieve the best application state thereby.

Please refer to FIG. 1. A conventional cellular shade 10 comprises a head rail 11, a bottom rail 12, and a plurality of interconnected hollow and hexagonal cellular pieces 13 sequentially arranged from top to bottom and fixed between the head rail 11 and the bottom rail 12 thereof to form a honeycomb shade wherein the cellular pieces 13 can be freely raised or lowered via a lift cord 14 in the collection or expansion operation thereof.

There are some drawbacks to such conventional cellular shade 10. First, no matter the cellular shade 10 is fully expanded as shown in FIG. 1 or collected as shown in FIG. 2, both lateral edges of each cellular piece 13 are symmetrically folded into bends of identical length, which can easily accumulate dust at both bending spots therein. Thus, each cellular piece 13 must be carefully cleaned from both lateral edges, which can take a lot of time and efforts and increase the difficulty and inconvenience in the cleaning thereof. Second, due to the lack of any support design, when the cellular shade 10 is fully expanded, the cellular pieces 13 tends to display in an uneven manner with some of the cellular pieces 13 fully expanded and some partially unfolded, which can ruin the look of the cellular shade 10 as a whole and reduce its decorative effect in display.

SUMMARY OF THE PRESENT INVENTION

It is, therefore, the primary purpose of the present invention to provide an enclosed-type cellular shade structure, including a plurality of interconnected cellular pieces uniformly arranged from top to bottom and fixed between a head rail and a bottom rail to form an enclosed-type cellular shade wherein both side edges of each cellular piece are defined by a long bent section and a short bent section with a coupling end and a fixing end respectively disposed thereon so that, when the enclosed-type cellular shade is fully expanded, the short bent sections connected by the fixing ends thereof will be appropriately stretched into a flat surface that can be simply flapped to remove dust there-from. Thus, only a patterned surface disposed at the long bent sections thereof is required to be wiped and cleaned, economically saving time and efforts in the cleaning thereof to achieve the best application state.

It is, therefore, the second purpose of the present invention to provide an enclosed-type cellular shade structure wherein, when the cellular shade is fully expanded, the short bent sections connected by the fixing ends thereof are appropriately stretched into a flat surface to form a locating support thereby so that the long bent sections disposed at the other side thereof can be sequentially unfolded and accurately displayed in an even and consecutive transverse V-shaped patterned surface, facilitating better visual effect and a uniform expansion of the present invention thereby.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer to FIG. 3. The present invention is related to an enclosed-type cellular shade structure, including a head rail 21, a bottom rail 22, and a plurality of interconnected cellular pieces 23 that, uniformly arranged from top to bottom between the head rail 21 and the bottom rail 22 thereof, are sequentially linked one to another to form a honeycomb and enclosed-type cellular shade 20 with free ends disposed at both end edges thereof, permitting the cellular pieces 23 to be raised or lowered by a lift cord 24 in the collection or expansion operation thereof. Both side edges of each cellular piece 23 are defined by a long bent section 231 and a short bent section 232 that, made in unequal length, are respectively equipped with a coupling end 233, and a fixing end 234 of identical length to be securely attached to the bottom surface of each immediate upper cellular piece 23 thereby. Therefore, the unequal length design of the long and short bent sections 231, 232 of each cellular piece 23 is cooperatively operated with the assembly of the coupling and fixing ends 233, 234 thereof. When the enclosed-type cellular shade 20 is fully expanded, the short bent sections 232 disposed at one side of the cellular shade 20 thereof are precisely connected by the fixing ends 234 thereof and appropriately stretched into a flat surface 201 as shown in FIG. 4. Besides, the stretched cellular pieces 23 will sequentially unfold in an equal space to form an evenly expanded enclosed-type cellular shade 20, permitting the long bent sections 231 disposed at the other side of the cellular shade 20 thereof to unfold in a consecutive and uniform transverse V-shaped patterned surface 202 thereby. Thus, the flat surface 201 of the enclosed-type cellular shade 20 can be simply flapped to remove the dust there-from in an easy manner, and only the patterned surface 202 disposed at the other side thereof is required to be wiped and cleaned, economically saving both time and efforts in the cleaning of the cellular shade 20 as well as reinforcing an even expansion of the cellular pieces 23 to achieve the best state of application thereof.

Moreover, the coupling end 233 and the fixing end 234 of each cellular piece 23 can be symmetrically arranged to extend inwards as shown in FIG. 3 or bent to extend outwards as shown in FIG. 5. Otherwise, the coupling end 233 and the fixing end 234 thereof can also be correspondingly folded to extend towards the same direction like towards the left side as shown in FIG. 6, or towards the right side as shown in FIG. 7.
